【产品】新型金属混合PPTC装置MHP-TAC，有助于提供自恢复过热保护

时间： 2018-12-30 来源：Littelfuse

技术问答

新型金属混合PPTC装置MHP-TAC提供较高的额定电压(12V直流电压)，相比典型的MHP-TAM器件外形更加小巧。 MHP-TAC有助于达到高容量锂（离子）聚合物和方型电池的电池安全要求，这种电池被应用于台式电脑、平板电脑和智能手机等大多数移动设备中。MHP技术将双金属保护器与聚合物正温度系数(PPTC)设备并联。 PPTC可发挥加热器的作用，并在故障排除前将双金属闭锁。 MHP-TAC有助于提供自恢复过热保护。

电流-温度曲线

（电流-温度曲线来自于将测试样品置于25°C，40°C，60°C，70°C，75°C和80°C的烘箱中，以0.1 A /分钟的速率增加通过样品的电流并记录样品跳闸时的当前值）

电气特性的注意事项

1. 设备电气特性可能会因为安装条件而发生改变。用户应独立评估每种产品在其应用中的适用性。
2. 如果给器件添加任何终端或引线延伸，特别是在高电流放电的情况下，由于焊接方法或材料的变化，器件性能可能会受到负面影响。请避免会使得引线延长线的接头周围或延长终端产生大量热量的设计。
3. 不允许使用SMT回流焊，波峰焊和手工焊接。

使用中关于额定参数的注意事项
1. 电源电压必须小于额定电压。高于额定电压的操作可能导致器件损坏，冒烟或起火。
2. 器件保持电流高于电路中的正常电流值，并且器件跳闸电流低于异常电流值。对实际应用电路，如果选择太小的器件保持电流和跳闸电流值可能会使电路在正常使用条件下发生电路中断。
3. 本产品不应用于短路情况下可能超过最大中断电流的应用中。
4. 这些器件主要是用于防止偶尔出现过电流或过温故障引起的损坏，重复故障或长时间跳闸的情况不适合使用。如果在器件处于跳闸状态或暴露在超过100°C的温度条件下施加机械压力，器件可能无法正常工作。

使用中的环境要求
该设备用于通用电子设备常见的应用环境。在下面列出的任何特殊环境或条件下使用可能会对设备性能产生负面影响，因此用户在将此器件整合到任何设计中时应仔细考虑最终产品的使用条件以及对可靠性或性能的潜在影响，以便仔细检查设备的实际性能和可靠性。
•设备暴露于水，油，化学溶液和/或有机溶剂的环境。
•安装在靠近热源的区域或靠近易燃物体（如塑料线）附近。
•设备受压力，密封或树脂涂层约束的环境。
•水凝结在器件上的环境。
•有盐空气或有腐蚀性气体的环境，如CL₂，H₂S，NH₃，SO₂和NO_X。
•有砂砾和灰尘和/或阳光直射的环境。
•超出推荐工作温度的环境。
